ENIO is offering a smart plant protection device, which covers the plant with a shield made of ozone, the same molecule our planet uses to protect the nature from extrusive effects. It is an integrated (totally automated) smart device capable of delivering ozone dissolved in water, fined tuned with respect to environmental data analysis of agricultural food production fields. The environmental variables such as temperature and humidity can be modeled as the proliferation & spread potential of harmful pathogens. When this fact is merged with the scientific observation that plants can be safe from ozone under certain limits, a unique approach of data-dependent plant protection with ozone is born. The key point in system design is the ozone concentration output feeding the closed-loop control, which is provided by saturated ozone sensor. This state-of-art device is developed by us as well.
